RoLLER SIDE BEARING.

1,396,014. p e i A- Application Vled` November To aZZ whom t may concern: v Y.

Be it known that I, FRANKLIN L. BARBER, a citizen of the United States, rresiding at Chicago, in the county ofCook Vand State of Illinois, have invented certain Ynew and useful Improvements in Roller Side Bearings; and I do hereby declare the following to be a full, clear, and exact' description of the in. y others` skilled in the art to which' it appertains to 'make and.

vention, such as'will enable use thesame.

Thisinvention relates .to a roller bearing and particularly toaside vbearing for railway cars, which bearing is adapted-to be carried Vby the body bolster ofthe car to bear upon the wearing surface ofthetruck bolster. g j

It is an object of this invention to provide such a bearing of rugged construction, few and simple parts, and `one which will autoV matically'tendv toresume and maintain its normal position.

This, and other object-Is: and advantages ofthe invention will appearas the'description proceeds in connection with the accompanying drawings, in which like reference characters refer to the same different views, and in which, y

Figure 1 is a view in side elevation of the bearing; j 'Y Y. f Fig. 2 is a partial bottom plan view thereof; and i ,j l Fig.k 3 is a view in elevation of the device as seen from theV right of F 1, a portion of the device being shownlin section. e Referring -to the drawings, -the device comprises a supporting member 1 shown as provided with a base flangehaving four diverging and symmetricallyarranged lugs 2.7Each of these lugs is yprovided with a raised finishing boss throughfwhich pass the holes 3 adapted to receive securing bolts or screws. The said flange is formed on an incline, or

with a batter, as clearly shown in Fig. 3, to conform to the shape of the car body bolster.

y Depending from the base Vflange of member l and spaced therefrom is a second flange member 4. This flange extends across the ends of the member 1, as shown in Figs. 2 and 3, and isv of the same conformation as the iange 5 which is arranged to contact therewith and be secured thereto by the Anutted bolts 6. The flange 5 is carried by a housing member 7 having a base of general rectangular shape adapted to be received within the Specification of Letters -Patent.

depending lianges 8 of'member 1. The member 7 also has depending parallel sides and curved end portions which are clearly seen as 9 in Fig. 1.Y An elongated horizontally disposed opening 10 -is formed in the said depending side portions of the member 7, which opening-is shown as surrounded by a The-member '7 has portions 7 projecting at each side thereof, which are/received in thev recesses formed by ianges 8,and these projections are formed along theirlower edge at the outer portion thereof, with' rack teeth 12. The member 1 is also formed with a central rectangular recess adapted to receive a rectangular wear 'ing plate 13.

Vof said member the counterweight members 1,5.f Pin 14 is headed at one end and suitably threaded at the other tov receive anut and proper-pou washer to hold the members 15 in sition. The pin 14 also passes through a central opening inv a roller member 16 which is disposed between the sides'of the member 7 and which has cylindrical projections 17 aty each end Athereof arranged to be received in the elongated slots or openings 10. The counterweight members 15 have openings of larger diameterthanthe pin 14 to V4loosely engage the same andare formed below said pm with an enlarged counterweight portion land above said pin are formed as a quadrant having the radial teeth 15?. These teethasshown inFi'gs. 1 and 3.are arranged to engage with. the yrack teeth 12 carried byy member 7. It will be noted that the roller er side against the surfaceof plate 13, and lower side, said roller projects beyond the member 7 and is designed to bear upon the wearing surface of the truck bolster. The rollermember 16 is cored or bored to loosely fit the pin 14.

When relative motion occurs between the body bolster and truck bolster, as when the vcar is going around a curve, the roller member will be traversed along faces and the counterweight befswung into an angular position relative to that shownin Fig. l, by the engagement of the gear teeth thereon with the rack teeth on member 7,' said member swinging about the axis vof pin 14. When the bearing surthe bearing surmember 15 will gear " *face isk again moved to resume normal positionlthe countervveight member 15v will tend iol v bled7 the roller member 16'Will bedropped.
